如何获取当前时间?
当前回答
now()的属性可用于获取python中的当前时间:
# importing datetime module for now()
import datetime
# using now() to get current time
current_time = datetime.datetime.now()
# Printing attributes of now().
print ("The attributes of now() are : ")
print ("Year : ", end = "")
print (current_time.year)
print ("Month : ", end = "")
print (current_time.month)
print ("Day : ", end = "")
print (current_time.day)
print ("Hour : ", end = "")
print (current_time.hour)
print ("Minute : ", end = "")
print (current_time.minute)
print ("Second : ", end = "")
print (current_time.second)
print ("Microsecond : ", end = "")
print (current_time.microsecond)
其他回答
如果需要当前时间作为时间对象:
>>> import datetime
>>> now = datetime.datetime.now()
>>> datetime.time(now.hour, now.minute, now.second)
datetime.time(11, 23, 44)
获取当前日期时间属性:
import datetime
currentDT = datetime.datetime.now()
print ("Current Year is: %d" % currentDT.year)
print ("Current Month is: %d" % currentDT.month)
print ("Current Day is: %d" % currentDT.day)
print ("Current Hour is: %d" % currentDT.hour)
print ("Current Minute is: %d" % currentDT.minute)
print ("Current Second is: %d" % currentDT.second)
print ("Current Microsecond is: %d" % currentDT.microsecond)
#!/usr/bin/python
import time;
ticks = time.time()
print "Number of ticks since "12:00am, Jan 1, 1970":", ticks
方法1:从系统datetime获取当前日期和时间
datetime模块提供用于操作日期和时间的类。
密码
from datetime import datetime,date
print("Date: "+str(date.today().year)+"-"+str(date.today().month)+"-"+str(date.today().day))
print("Year: "+str(date.today().year))
print("Month: "+str(date.today().month))
print("Day: "+str(date.today().day)+"\n")
print("Time: "+str(datetime.today().hour)+":"+str(datetime.today().minute)+":"+str(datetime.today().second))
print("Hour: "+str(datetime.today().hour))
print("Minute: "+str(datetime.today().minute))
print("Second: "+str(datetime.today().second))
print("MilliSecond: "+str(datetime.today().microsecond))
输出将如下
Date: 2020-4-18
Year: 2020
Month: 4
Day: 18
Time: 19:30:5
Hour: 19
Minute: 30
Second: 5
MilliSecond: 836071
方法2:如果网络可用,则获取当前日期和时间
urllib包帮助我们处理url,即网页。这里我们从网页收集数据http://just-the-time.appspot.com/并使用包日期解析器从网页解析日期时间。
密码
from urllib.request import urlopen
import dateparser
time_url = urlopen(u'http://just-the-time.appspot.com/')
datetime = time_url.read().decode("utf-8", errors="ignore").split(' ')[:-1]
date = datetime[0]
time = datetime[1]
print("Date: "+str(date))
print("Year: "+str(date.split('-')[0]))
print("Month: "+str(date.split('-')[1]))
print("Day: "+str(date.split('-')[2])+'\n')
print("Time: "+str(time))
print("Hour: "+str(time.split(':')[0]))
print("Minute: "+str(time.split(':')[1]))
print("Second: "+str(time.split(':')[2]))
输出将如下
Date: 2020-04-18
Year: 2020
Month: 04
Day: 18
Time: 14:17:10
Hour: 14
Minute: 17
Second: 10
方法3:从机器的本地时间获取当前日期和时间
Python的时间模块提供了一个函数,用于从称为localtime()的历元起经过的秒数获取本地时间。ctime()函数将从epoch开始经过的秒数作为参数,并返回表示本地时间的字符串。
密码
from time import time, ctime
datetime = ctime(time()).split(' ')
print("Date: "+str(datetime[4])+"-"+str(datetime[1])+"-"+str(datetime[2]))
print("Year: "+str(datetime[4]))
print("Month: "+str(datetime[1]))
print("Day: "+str(datetime[2]))
print("Week Day: "+str(datetime[0])+'\n')
print("Time: "+str(datetime[3]))
print("Hour: "+str(datetime[3]).split(':')[0])
print("Minute: "+str(datetime[3]).split(':')[1])
print("Second: "+str(datetime[3]).split(':')[2])
输出将如下
Date: 2020-Apr-18
Year: 2020
Month: Apr
Day: 18
Week Day: Sat
Time: 19:30:20
Hour: 19
Minute: 30
Second: 20
.iformat()在文档中,但这里还没有(这与@Ray Vega的回答非常相似):
>>> import datetime
>>> datetime.datetime.now().isoformat()
'2013-06-24T20:35:55.982000'
您可以使用此函数获取时间(遗憾的是,它没有显示AM或PM):
def gettime():
from datetime import datetime
return ((str(datetime.now())).split(' ')[1]).split('.')[0]
要获取稍后要合并的小时、分钟、秒和毫秒,可以使用以下函数:
小时:
def gethour():
from datetime import datetime
return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[0]
分钟:
def getminute():
from datetime import datetime
return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[1]
第二:
def getsecond():
from datetime import datetime
return (((str(datetime.now())).split(' ')[1]).split('.')[0]).split(':')[2]
毫秒:
def getmillisecond():
from datetime import datetime
return (str(datetime.now())).split('.')[1]
